UT4026 Geotextile vertical permeability meter is used to determine the vertical permeability performance of geotextiles and their related products under the constant head method. The head of this type of geotextile vertical permeability meter can be adjusted (0-300mm), and can maintain a stable head, and the geosynthetic material permeation test equipment is designed to reduce the head loss, and the box-shaped structure is adopted.
Standard: EN ISO 11058:2019 Geotextiles and geotextile-related products - Determination of water permeability characteristics normal to the plane, without load.
ASTM D4491 Standard Test Methods for Water Permeability of Geotextiles by Permittivity
Feature:
1. The permeability coefficient is automatically calculated, and the head height is automatically positioned.
2. Loading samples in water to avoid bubbles during the test and affecting the test results.
3. Special rapid sampling tool, fast loading and high efficiency.
4. Transparent plexiglass test chamber is adopted, which is not rusty, and the test process is convenient for observation.
